Well, I managed to get permission to hunt an old home site today, and had nothing but bad luck.  The house was built in 1820, and was standing until the property was purchased and used as a cow pasture in the early 1970's.  I went out, all excited, and hoping to find my first IH penny.  Just as soon as I got on the property, my BH QD2 started singing, indicating a dime at 4".  Repeated in all directions, and not fluctuating.  I dug only to find what looks to have been a vienna wiener can.  I covered the hole and put the can on top, and moved on. Long story short, my detector read either dimes or quarters on lots of cans.  All were the aluminum looking cans, but the short 2" tall by about 2" diameter. I was getting the same readings on badly rusted pieces of roof tin that was in the area as well.  I came home, laid coins out on the ground, and ran the coil over them.  The detector reads correctly on these.  My last detector adventure landed lots of clad, and seemed to be pretty accurate about the coin and the depth.  Is there any chance that the ground is badly mineralized and causing the detector to be confused?  I tried hunting the quickdraw II in all metal, disc, and auto disc.  I had the sensitivity set at about 3 o'clock, with the disc at about 10 o'clock.  This was with the initial setting.  I tried everything I could think of, even turning the sensitivity down as low as possible, and disc turned to 100%.  Nothing worked.  Is this just one of those things I have to learn to live with?  Do I need to go out and get a better unit?  At this point, I'm having enough fun that I don't mind sinking a little money in a higher end detector, but if it isn't necessary, I'd prefer to just keep using this one.  So, what do you veteran hunters suggest?
Thanks in advance.

 With all the good things that came with aluminum, in the metal detecting world, it has many times been a curse. Monday evening, I quickly checked a very small dirt turn out along the river side of the highway to see what I could find. It did not take long and I found one quarter and three pennies. Then came the aluminum pieces. Most pieces were about 1/16" thick and 3/4" wide and broken into about 1-1 1/2" or give or take lengths. They were all over in about a 10' area. The sun was going down quickly behind the mountain so it came down to two things, spend the time to search and clean out all the junk or leave the junk and search more of where it was not before dark fell on me. In that 10' area, it is possible that there may be a coin or two but I have no reason to believe they would be old because the highway is not that old.
